Syntax

Definition:

FUNCTION F_VN_Reduce : HRESULT
VAR_INPUT
    ipSrcImage  : ITcVnImage;
    ipDestImage : Reference To  ITcVnImage;
    nDim        : DINT;
    eReduceType : ETcVnReduceType;
    hrPrev      : HRESULT;
END_VAR

Inputs

Name	Type	Description
ipSrcImage	ITcVnImage	Source image (USINT or REAL elements, 1 channel)
ipDestImage	Reference To ITcVnImage	Destination image. If ipSrcImage is of type USINT and the reduction type is SUM or AVG, ipDestImage will be of type REAL; otherwise, it retains the same type as ipSrcImage (An appropriate single channel destination image will be created if required.)
nDim	DINT	Index along which the ITcVnImage is reduced: 0 reduces the matrix to a single row, 1 reduces it to a single column
eReduceType	ETcVnReduceType	Reduction operation
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
